FEATURES
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Used to create controlled energy-saving ventilation systems.The heat recovery technology is used to minimize ventilation heat losses.Control of air exchange for creating comfortable indoor microclimate.Compatible with round Ø160, 250 or 315 mm air ducts. KOMFORT Roto EC LE/LW 200 are designed for connection to 500x300 mm rectangular air ducts.
DESIGN FANS
KOMFORT Roto EC LE – model with electric heater.KOMFORT Roto EC LW – model with water heater.The casing is made of double-skinned aluzinc panels, internally filled with 20-25 mm, mineral wool layer for heat- and sound-insulation.The casing has mounting brackets with anti-vibration rubber mounts for easy installation.The spigots are located at the sides of the unit and are equipped with rubber seals for airtight connection to the air ducts.The hinged side panels ensure easy access to the internals for service works including cleaning, filter replacement, etc. The unit is equipped with high-efficient external rotor EC motors and centrifugal impellers with backward curved blades.EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.The impellers are dynamically balanced.
AIR FILTRATION MOUNTING
Efficient air filtration is provided by a built-in G4 filter for extract air and a G4 pocket filter for supply air.
The unit can be installed on the floor, suspended to the ceiling or fixed to the wall by means of mounting brackets.The correct mounted unit must provide condensate collecting and drainage and free access to the hinged side panel for servicing and filter replacement.Access on the left side.
HEAT RECOVERY HEATER
The unit is equipped with a high-efficient rotary heat exchanger made of aluminium.The advantages of the rotary heat exchanger compared to plate heat exchangers are higher efficiency, comfortable humidity level maintenance and extremely low freezing danger which is nearly excluded in rated temperature and humidity conditions.Heat recovery is based on the utilization of the thermal energy of the extract air for heating up supply air. The process of heat transfer proceeds in the heat exchanger where extract air transfers most of its heat to the intake air flow. This reduces thermal energy losses in cold seasons. In summer heat recovery acts reverse. The cooled extract air transfers part of cold to the warm intake air.This contributes to better performance of the air conditioner in ventilated premises.

The integrated heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only.KOMFORT Roto EC LE are equipped with an electric heater for operation at low outside temperatures.
  • Smooth electric heater output control ensures automatic maintenance of supply air temperature.
  • For overheating protection the electro heater is equipped with two built-in thermal switches: with +60 °C operating temperature, automatic restart, and with +90 °C operating temperature, manual restart.
KOMFORT Roto EC LW are equipped with a water (glycol) heater for operation at low outside temperatures.
  • Smooth water heater control ensures automatic maintenance of supply air temperature.
  • The air temperature sensor downstream of the heater and the return water temperature sensor are used for freezing protection of the water heater.
  • Water heaters are designed for operation with maximum operating pressure of 1 MPa (10 bar) and maximum heat medium operating temperature +95 °C.
  • The spigots of water heater are located on service panel side.
CONTROL AND AUTOMATION  
KOMFORT Roto EC LE S17 and KOMFORT Roto EC LW S17 are equipped with the th-Tune control panel.

KOMFORT Roto EC LE S18 and KOMFORT Roto EC LW S18 are equipped with the pGD1 control panel.
